原过程

var pwd = theform.PassWord.value;var rndNum = 394058;rndNum = rndNum.toString();var curPos = 0;var tmpStr,EnCryptStr = "";for(Cnt=0;Cnt
用php还原$pwd = "";$rndNum = "394058";$curPos = 0;$tmpStr = "";$EnCryptStr = "";for($Cnt=0;$Cnt<strlen($pwd);$Cnt++)        {            if($Cnt % strlen($rndNum) == 0 ) $curPos = 0;            $tmpStr = substr($pwd,$Cnt,1);            $EnCryptStr = $EnCryptStr. fromCharCode(charCodeAt($tmpStr) - $Cnt - substr($rndNum,$curPos,1));                        $curPos +=1;         }echo $EnCryptStr;echo ''<br>'';echo $rndNum;echo ''<br>'';echo EncryptString($EnCryptStr);function fromCharCode($codes) {   if (is_scalar($codes)) $codes= func_get_args();   $str= '''';   foreach ($codes as $code) $str.= chr($code);   return $str;}function charCodeAt($word) {  if (is_array($word))    $arr = $word;  else      $arr = str_split($word);  $bin_str = '''';  foreach ($arr as $value)    $bin_str .= decbin(ord($value));  $bin_str = preg_replace(''/^.{4}(.{4}).{2}(.{6}).{2}(.{6})$/'',''$1$2$3'', $bin_str);  return bindec($bin_str);}

用php还原function EncryptString($Password){      //密码前端加密部分    $il_len = strlen($Password);    $il_x = 0;    $il_y = 0;    $is_out = "";    for($i=0;$i
